RESERVOIR BLACKlNG-BRUSH.-

ESPECIPIC'ATION forming part of Letters Patent No. 354,545, dated December 21, 1886.

Application filed March 20, 1886.

To all whom it may concern:

Be it known that I, J OHN T. GAIGE, of Penn Yan, in the county of Yates, in the State of New York, have invented a certain new and useful Improvement in Reservoir Blacking- Brushes, of which the following is a specifica tion.

My improvement is intended to serve with liquid blacking supplied in a reservoir adjacent to the brush which applies the blacking. I have devised import-ant improvements in the means for controlling the flow from the reservoir to'the brush and insuring against accidental opening, and in preventing mischief in case the control is not perfect and blacking shall leak into the brush. I can attach the whole to the back of an ordinary polishing brush, and will describe it as thus applied.

The accompanying drawings form a part of this specification.

Figurcl is a longitudinal section, partly in elevation. Fig. 2 is a transverse section on the line a a: in Fig. 1. These figures show the cap applied, and the device is in condition for packing and transportation. View showing the brush with the cap removed. A portion of the center of the brush is represented as broken away to show the mouth of the tube and the clearing-wire therein.

Similar letters of reference indicate corresponding parts in all the figures where they occur.

A is the main body of the reservoir, formed of sheet metal-as tinned sheet-iron.

A is the rim around the filling-aperture, tightly stopped by a plug, 1?. A short tube or rim, A incloses a packing,a, of leather or other suitable material, in which the operating-shaft rocks.

B is a thick circular disk of firm wood. It receives bristles C, and with them constitutes the blackingrbrush. The center is bored, as shown.

D Dis a cover, the lower portion, D, cylindrical and fitting tightly around the part B of the reservoir. The upper portion, D, is a frustum of a cone with the top tightly covered and applied against the edges of the bristles C, so as to draw them together and keep the brushfrom spreading or being crushed down at one side by use.

E is the base, and F the bristles, of an or- Fig. 3 is aplan soldered thereto at the outer end.

dinary polishing-brush. Itis secured to A by nails G, driven through a hanging lip, A, and

by screws H through an extension, A*. These screws also attach a handle, I, which performs its usual functions. A hole in the center of the wood B, re-enforced by a short tube, 1), allows the liquid blacking to fiow from the reservoir to be distributed among the bristles 0 whenever the device is inverted and the valve is open. J is the valve. It is a thick disk of cork or analogous material, which,wh en closed, is pressed tightly against the lower end of the tube b, and accommodates itself thereto.

K is a wire, of hard iron or steel,extending centrally through the valve J. An extension, K, plays in the tube 1). Its lower end is formed as an eye, which is engaged bya crank, M, in a shaft, M, composed of a sufficiently-stout wire which extends out through the packing a, and is cranked near the extreme outer end, as indicated by M". This shaft has a bearing in the handle I at I, also a bearing in the interior of the reservoirin the loop of the wire A. A metallic disk. K soldered on K, supports the valve J. The valve is guided to its seat by a metal piece, A", Fig. 2, which passes through an extension of the disk K.

A smaller wire, L, of steel or hard brass, is wound many times around the shaft M and An arm, L, at its inner end, engages in a notch in the rim A. These parts are so adjusted that the spring L exerts a constant force, turning the shaft M in the direction to press upward the arm M and hold the valve J firmly againstits seat. This coiled wire L turns the shaftby its tendency to unwind. It performs another function by its tendency to thrust endwise relatively to the shaft M. This second function is the compression of the packing a. The force of the spring acting endwise against a disk, at, upon the packing keeps the packing compressed, and thus causes it to fit tightly around the shaft even after long wear.

It is important to insure that the valve is held tightly to its seat when the brush is packed in a trunk with good clothing. I attain this bya locking-hook, N, pivoted to the handle I at the point I". When the brush is in use, this hook is disengaged and allowed to stand in the position shown in dotted lines in Fig. 2. The shaft M may now be turned by acting on the crank 1W by the thumb or finger at intervals, as judged expedient, in order to keep the bristles O properly supplied with the liquid blacking. When the brush is simply laid aside, the hook N may be still neglected; but when the brush is to be packed in a trunk and is liable to stand in all positions, the valve J is pressed tightly to its seat, not only by the force of the springL, but also by an additional force received from the hook N, which is now brought into position and engaged with the end of the crank M. This conditionis shown in strong lines in Figs. 1 and 8.

The reservoir is filled througha filling-hole, A, and the plug P inserted. The cap D D being tightly fitted, the device may be packed with safety in a trunk, or otherwise stored. When it is desired for use, the cap D D is removed and the device inverted, and the shaft M being rocked by the application of the thumb to the crank M", the valve J is drawn inward (in the inverted position of the parts this will be upward) and the wire K K, moving in b, insures that the passage is clear for the blacking to flow from the reservoir to supply the brush B G, which may now be worked in the usual manner. Reversing the position of the device and again applying the cap D D, the whole is conditioned for storage again, as before.

The shaft M, with its cranks M and M and spring L, affords a reliable and convenientlyoperating means of working the valve. The wire K K connects the valve J to the crankarm M, guides the valve to its seat, and by its compound longitudinal and lateral movements, due to the circular motion of its lower end, insures a sufficient passage for the blacking, no matter how much it may dry up. The conical form of the part D of the cap draws the bristles 0 together and holds them properly supported. The cylindrical part D of the cap matches tightly and reliably aroundthe corresponding portion of the reservoir. This cap holds the bristles in the correct position, prevents them from coming in contact with other articles when the brush is packed, prevents the blacking in the brush from drying up, and performs an especially important function in preventing mischief if the valve leaks while the brush is in a position to allow the fluid to flow past it.

Modifications may be made in the forms and proportions Without departing from the principle or sacrificing the advantages of the invention. The plugP may be screw-threaded and engage in a correspondingly-tapped rim.

I claim as my invention- 1. In a reservoir blacking-brush, the valve J, wire K, shaft M, crank M, spring L, notched tube A", and packing a, in combination with each other and with a blacking reservoir and brush, as herein specified.

2. In a reservoir blacking-brush, the hook N, turning on a pivot, I in combination with the handle I, double-cranked shaft M M 1W, reservoir A, valve J, and brush B 0, arranged for joint operation, as herein specified.

3. The extension K of the wire K, arranged as shown, and combined with the crank M and operating means therefor, and with the valve J, reservoir A B, and blacking-brush B G, as herein specified.

In testimony whereof I have hereunto set my hand, at Penn Yan, Yates county,New

York, this 16th day of March, 1886, in the \Vitnesses:
